14.5 Reservation of Tool Wear Compensation (Lathe System)

14.5.3 Usage Examples

When you execute a machining program from the top to M99 without rewriting tool wear compensation memory, and then
rewrite the tool wear compensation memory during repetition of the program.
(1) Set the parameter "#8140 Reserve T wear com" to "1", then turn ON the power again.
(2) Turn ON the "Reservation of tool wear compensation" signal (Y1CB8).
(3) Perform continuous operation of the following machining program.

(*1) Assume that M50 command turns ON "Request for reflecting reserved tool wear compensation" signal (YD0F)
through the ladder logic.
(4) Set the reserved value between the N01 and the N14 blocks.
(5) All the reserved values set between the N01 and the N14 blocks are reflected simultaneously in the tool wear compensa-
tion memory at the N15 block.

14.5.4 Precautions

(1) The tool offset change history is updated when the reserved tool wear compensation memory has been reflected in the
tool wear compensation memory.
(2) When the tool compensation data is deleted by deleting all tools, the reserved tool wear compensation data is also
deleted simultaneously.
